development and validation of a multi-target, blood-based nafld diagnosis test

Conditions: NAFLD; NASH - Nonalcoholic Steatohepatitis

Summary: multi-omics approach was used to identify patterns of serological biomarkers to diagnose nafld. the purpose of this study is to develop and validate a blood-based assay to diagnose nafld by collecting blood sample from healthy patients undergoing routine screening ultrasonography and from patients recently diagnosed with nafld.

accurate diagnosis of nafld combined with effective treatment improves survival and quality of life. multi-omics approach was used to identify patterns of serological biomarkers to diagnose nafld. the purpose of this study is to develop and validate a blood-based assay for accurate diagnosis of nafld. the study will collect blood sample from healthy patients undergoing routine screening ultrasonography and from patients recently diagnosed with nafld. a blood-based test for nafld could offer an accurate, convenient, and patient-friendly screening option for current and future generations, and, in doing so, could save and improve lives by increasing adherence and accurate diagnosis. three types of patients in this study: cohort a: people ages 20-85 who have been recently diagnosed with (or strong clinical suspicion for) nafld. blood samples must be collected before any treatment has been initiated. cohort b: people ages 20-85 undergoing routine screening ultrasonography for nafld as part of their regular medical check-ups. blood samples must be collected before ultrasonography. cohort c: people ages 20-85 who have been recently diagnosed with (or strong clinical suspicion for) nash, an extremely advanced form of non-alcoholic fatty liver disease (nafld), is defined as hepatic steatosis with inflammation and hepatocyte injury. blood samples must be collected before any treatment has been initiated.

Eligibility criteria:
